This invention relates to; wrenches and more particularly'toawrenchadapted for use when Connecting o1- threaded pipe sections. p

1 One object of the inventionfis to so construct the wrench that one pipe-section or connects the-two wrenches l and 2iincludes 1 I a handle12 which extends longitudinally of the-shank 5 ofthe stationa-ry jaw of wrench 2van'dJha-sits' forwardend portion fitted'into v a; 'SOOketI 1 3 t and. releasably held in; the socket by means of latch pin l lslidably mounted in ent enin f edia h ek tiia d I yieldahly held in position to enter" a selected I 1:
